St-George spirits in Alameda CA makes a great gin called Terrior that is infused with Douglas Fir for a unique smell and taste. They also have a Rye Gin which is aged in oak barrels resulting in a darker colour and a hint of whisky flavour. St. George Spirits :: St. George Dry Rye Gin

If you're trying a gin fizz, check out Malfy Gin from France, it's got a bit of grapefruit flavour which adds to citrus drinks.

I like to make my Hendricks and tonic (or Hendricks & soda) with some cucumber puree instead of lime. I freeze it ahead of time in an icecube tray for easy use.
